Bicycle Helmet Design Experiment

1. Divide students into groups.
2. Give each group a boiled egg and a hunk of Play-Doh.
3. Ask them to design bicycle safety helmets where the boiled egg models the bicycle  rider's skull.
4. Designs are judged by simply dropping each construct on the floor from waist height and  seeing which eggs break.

This demo is simple, fun, and rather illustrative of the use of modeling to help solve  engineering problems.

Thanks to Victoria Heil in Arizona for providing this activity idea.
